I have an rewarded app in which users earn points by doing some activities and then they finally redeem as money.But i am getting too many fake redeem requests… i think some of hackers send send fake redeem request to firebase. So i am not able to give points to genuine users. Is there any way where i can track the activity of users in app.
Count number of clicks, using the OnClick events and a TinyDB. That’s simple and effective, since faking taps is harder than changing system time. 
P.S. Don’t forget to mark this as solution to close the question, if the problem is solved.
